My 1951 GMC did not come to me with an engine. I found an old one, had it rebuilt and it's now ready to mount into the frame. So here is the questions... Is there a hardware specifications manual anywhere that I can determine what bolts are required to mount my rebuilt 228 to the front and two side mounts? I'm ready to go but don't know what size grade 8's to use. Your help would be greatly appreciated!
